I recently recorded an interview in Logic Pro X which lasted for over an hour. Before the actual interview, I had run several short ~2 minute tests to ensure the recording was working properly. And my tests were good, I was able to confirm that the playback sounded good on my recordings.

However, on the real recording, which lasted for 1 hr, upon playback I heard noise (static/click) starting about 11 mins into the recording! :( The first 10 mins sounded great and without problems until 11 mins into the recording. The rest of the recording from 11 mins to 60 mins in has the same staticky/clicking noise sounds. I was so frustrated, as the recorded material cannot be used nor edited around.

Hardware / Software Context

iMac 27", Physical Drive (1TB) (APPLE HDD ST1000DM003)

Audio Interface: Focusrite Scarlett 2i4

Recording on 2 XLR inputs simultaneously

Logic Pro X v10.3.2

Using Aggregate Device

Using Multi-Output Device

More Context

I had attempted to also record a 3rd input, the computer audio, to capture the Google Hangout with which we were conducting the interview with Soundflower. But, I wasn't able to record any computer audio with Logic Pro X and Soundflower in my short tests.

Soundflower v2.0b2

Google Hangout running

Aggregate Device (for Scarlett 2i4 USB, Soundflower (2ch))

Clock Source: Soundflower

Multi-Output Device (for Scarlett 2i4 USB, Soundflower (2ch))

Clock Source: Soundflower

NOTE: We were monitoring the audio via the audio interface (rather than through Logic Pro X), and thus didn't hear any issues while recording.

Well, I was able to remove the noise static/clicking by changing the Aggregate Device Clock Source to Scarlett 2i4 USB.

Using Logic Pro X's Input Monitoring per track, I was able to hear the difference while recording.

Retoon Plays has a solution...

NOTE: And I also figured out how to record the computer system audio. My missing step was to set Mac System Output to Multi-Output Device or at least something including Soundflower (2ch). Formerly I was only toying with my DAW's input and output.
